Substitute Part Grouping Explanation

Substitution eligibility for the SN74AS760DW is determined by strict equivalence across the following critical parameters:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 4
• Output Type: Open Collector
• Current - Output Low: 64mA
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: 0°C ~ 70°C (TA)
• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into two categories:

MFR Recommended Substitute: SN74AS760DWR differs only in packaging format (Tape & Reel versus Tube) and product status (Active versus Last Time Buy), maintaining identical electrical and mechanical specifications.

Parametric Equivalents: SN74BCT760DW, SN74AS757DW, and SN74BCT757DW meet all critical electrical and mechanical parameters. These parts differ in series designation (74BCT versus 74AS) and base product number, reflecting internal design variations within the same functional class while maintaining full parameter compatibility.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using SN74AS760DW, the following selection criteria apply:

Primary Recommendation: SN74AS760DWR is the direct manufacturer-recommended substitute, offering identical electrical and mechanical specifications with Active product status. This part is preferred for new procurement due to its ongoing availability and Tape & Reel packaging format, which is standard for automated assembly operations.

Alternative Selections: SN74BCT760DW, SN74AS757DW, and SN74BCT757DW are parametric equivalents meeting all functional requirements. SN74BCT757DW carries Active product status, making it suitable for long-term design continuity. SN74BCT760DW and SN74AS757DW carry Last Time Buy status, similar to the original part, and should be evaluated based on current inventory availability and project timeline requirements.

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can SN74AS760DWR be used as a direct replacement for SN74AS760DW?

A: Yes. SN74AS760DWR is the manufacturer-recommended substitute with identical electrical specifications, operating parameters, and package dimensions. The only differences are packaging format (Tape & Reel versus Tube) and product status (Active versus Last Time Buy).

Q: What is the difference between 74AS and 74BCT series parts?

A: Both series meet the specified electrical and mechanical parameters for this application. The series designation reflects internal design architecture. SN74BCT757DW and SN74BCT760DW are parametric equivalents to their 74AS counterparts, maintaining identical output current, supply voltage, operating temperature, and package specifications.

Q: Are all substitute parts available in the same 20-SOIC package?

A: Yes. All listed substitute parts use the 20-SOIC (0.295", 7.50mm Width) package with surface mount configuration, ensuring mechanical compatibility with existing PCB designs.

Q: Which substitute part has the best long-term availability?

A: SN74BCT757DW carries Active product status, indicating ongoing manufacturer support and availability. SN74AS760DWR also carries Active status. Parts with Last Time Buy status (SN74AS760DW, SN74BCT760DW, SN74AS757DW) have limited production windows and should be evaluated based on current inventory levels.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All listed parts are ROHS3 compliant with MSL Level 1 rating, REACH Unaffected status, and identical ECCN and HTSUS classifications, ensuring regulatory and environmental compliance across all substitution options.

Q: What inventory levels are available for each part?

A: Current stock levels are SN74AS760DW (1047 pcs), SN74AS760DWR (2134 pcs), SN74BCT760DW (3400 pcs), SN74AS757DW (828 pcs), and SN74BCT757DW (821 pcs). Inventory availability should be confirmed at time of procurement.
